Can Navigation-assisted Surgery Help Achieve Negative Margins in Resection of Pelvic and Sacral Tumors?

CONCLUSIONS: Navigation-assisted resection of pelvic and sacral tumors resulted in a high likelihood of negative margin resection in this series, and we observed relatively few complications related specifically to the navigation. We have no comparison group without navigation, and future studies should indeed compare navigated with nonnavigated resection approaches in these anatomic locations. We did identify a potential navigation-related complication of femoral nerve palsy in this series and suggest careful placement and observation of the reference array during the operative procedure to lessen the likelihood of this previously unreported complication. We suggest it is worthwhile to consider the use of navigation-assisted surgery in resection of tumors of the pelvis and sacrum, but further study will be needed to determine its precise impact, if any, on local recurrence and other oncologic outcomes. LEVEL OF EVIDENCE: Level IV, therapeutic study. PMID: 29529631 [PubMed - in process]

CONCLUSIONS The findings from this study showed that the identifiable prognostic factors in patients with CCS were stage and tumor size. Local stage and tumor size ≤3 cm were favorable prognostic factors for patient survival in CCS. PMID: 31522190 [PubMed - in process]

il Jeoung Epidermal growth factor receptor (EGFR) plays critical roles in cell proliferation, tumorigenesis, and anti-cancer drug resistance. Overexpression and somatic mutations of EGFR result in enhanced cancer cell survival. Therefore, EGFR can be a target for the development of anti-cancer therapy. Patients with cancers, including non-small cell lung cancers (NSCLC), have been shown to response to EGFR-tyrosine kinase inhibitors (EGFR-TKIs) and anti-EGFR antibodies. However, resistance to these anti-EGFR treatments has developed. Autophagy has emerged as a potential mechanism involved in the acquired resistance to ...

In this study, a weighted co-expression network for ES was constructed through weighted gene co-expression network analysis to identify co-expression modules associated with clinical phenotypes. The hub genes in the metastasis- and OVS-related co-expression modules were extracted, and the association between the hub genes and patient OVS was verified in another independent Gene Expression Omnibus dataset. Functional annotations and protein-protein interaction analysis of co-expression modules were also used to understand the potential regulatory mechanisms. The results of the functional enrichment analysis revealed that th...

Authors: Gui W, Li J, Zhang Z, Wang L, Zhao J, Ma L, Su L Abstract The present case report investigated the clinical characteristics of primary hematological malignancy of the uterine cervixin five patients. Among the five patients, three patients were diagnosed with non-Hodgkin's lymphoma (NHL) and two patients with myeloid sarcoma (MS) of the uterine cervix. Biopsies of the uterine cervices demonstrated the involvement of lymphoid cells or myeloid blasts cells. Immunohistochemical staining demonstrated the expression of B-lymphoid and myeloid lineage markers. The associated lysozyme, myeloperoxidase and mast/stem...

In conclusion, our data suggest that ORF52 co-expression is effective for enhancing CRISPR/Cas9-mediated HDR, which may be useful for future studies involving precise genome editing. PMID: 31519773 [PubMed - as supplied by publisher]

ConclusionIncidence rates of STS and BS have been stable since 2001. The longer RS in STS can be attributed to advances in sarcoma patient management.

This study aims to provide the first epidemiological analysis of incidence and survival rates of STS in the Australian population.MethodsA retrospective population-based observational study was conducted between 1982 and 2009 of all patients with a diagnosis of STS using the Australian Institute of Health and Welfare (AIHW) Australian Cancer Database. Incidence rates per 100,000; incidence rate ratios, age-standardized incidence rates, prevalence and incidence rates of subtypes of STS, median, one-year and 5-year survival rates were examined.ResultsA total of 26,970 patients were identified. Between 1982 and 2009 STS incid...

Spindle cell rhabdomyosarcoma (RMS) is an aggressive sarcoma type with a predilection for the head and neck and frequent transactivating MYOD1 mutations. Malignant peripheral nerve sheath tumors (MPNST) show heterologous (most often rhabdomyoblastic) differentiation in 10% of cases; such tumors have been referred to as malignant “Triton” tumors. MPNST frequently harbors inactivating mutations in SUZ12 or EED, resulting in PRC2 dysfunction and loss of histone H3 lysine 27 trimethylation (H3K27me3), most often seen in sporadic and radiation-associated, high-grade tumors; immunohistochemistry (IHC) for H3K27me3 is...
